[ Upstream commit da22f0eea555baf9b0a84b52afe56db2052cfe8d ]

In olden times, closure_return() used to have a hidden return built in.
We removed the hidden return but forgot to add a new return here.  If
"c" were NULL we would oops on the next line, but fortunately "c" is
never NULL.  Let's just remove the if statement.

So this doesn't actually fix anything?
